Trincomalee Harbour, also known as Trincomalee Bay or Koddiyar Bay, is a large natural harbour situated on the north-east cost of Sri Lanka. Located in Trincomalee, Sri Lanka in the heart of the Indian Ocean, its strategic importance has shaped its recent history. There have been many sea battles to control the harbour. The Portuguese, Dutch, French, and the English have each held it in turn. In 1942 the Japanese Imperial Navy attacked Trincomalee harbour and sunk three British warship anchored there.
The harbour, the second largest natural harbor in the world, is overlooked by terraced highlands, and its entrance is guarded by two headlands. The harbour has 1630 hectares of water, while the entrance channel is 500 metres wide. The bay includes the first of a number submarine canyons, making Trincomalee one of the finest deep-sea harbors in the world.
